Abstract
La presente invención se refiere a un procedimiento para la producción continua de una resina de estireno modificada con caucho, que comprende suministrar de manera continua una solución alimentada compuesta principalmente de un monómero de estireno y un polímero de caucho a un primer reactor de tipo de mezclado perfecto y someterla a una reacción de polimerización, mientras se suministra continuamente una alimentación compuesta principalmente de un monómero de estireno a un segundo reactor del tipo útil para una reacción de polimerización y someterla a una reacción de polimerización, introduciendo los productos continuamente extraídos del primero y el segundo reactores, respectivamente, a un mezclador y mezclarlos, introduciendo el producto continuamente extraído del mezclador, a un reactor de tipo de flujo de tapón para aumentar la conversión mediante polimerización y luego desvolatilizar los monómeros no reaccionados del producto de reacción, en donde el polímero de caucho en el producto extraído del mezclador se encuentra ya en una forma particulada, pero capaz de salir del mezclador.The present invention relates to a process for the continuous production of a rubber modified styrene resin, which comprises continuously supplying a fed solution composed mainly of a styrene monomer and a rubber polymer to a first mixing type reactor perfect and subject it to a polymerization reaction, while continuously supplying a feed composed mainly of a styrene monomer to a second reactor of the type useful for a polymerization reaction and subjecting it to a polymerization reaction, introducing the products continuously extracted from the first and the second reactors, respectively, to a mixer and mixing them, introducing the product continuously withdrawn from the mixer, to a plug flow type reactor to increase the conversion by polymerization and then devolatilize the unreacted monomers of the reaction product, where the polyme The rubber in the product extracted from the mixer is already in a particulate form, but capable of leaving the mixer.
